Interesting routine. It's kind of an exact replication of any cold/ tarot card reading which makes it easy to memorize. I like to modify these routines by asking the girl what she thought about when she put the ring on today.
i.e.:
"Did you add this accessory because it helps get you laid? thats why I wear this bracelet. (ha ha ha) But seriously, my Grandma always told me to watch out for girls that put their ring on facing (whichever direction) on (whichever finger). She said it usually means either of two things: one, that the girl is falling out of love with her boyfriend, or two, is happy with her life as a whole but wants more out of some special aspect"

I like this approach because it's more than a routine. It's an example of my 30-second story technique. PUA analysts will tell you it has a NEG and a DHV spike. It screams honesty. I don't have to pretend to be a mystic or know some extensive ring placement theory. Finally it can lead into a deep conversation or be broken up by saying, "You'll never guess what grandma used to say about guys that wear bracelets on their left arm" (I call that a "Judge of Chemistry Line")
